Breakthroughs & Reverse Engineering (macOS Tahoe 26.7.1 / Darwin 25.6.0): - Reconstructed the complete 463-slot Skywalk vtable and class layout (0x128 / 296 bytes) of IO80211Controller (__ZTV17IO80211Controller at 0xffffff8002461148) and AppleBCMWLANCore from BootKernelExtensions.kc (IO80211Family 1200.13.1, source 1566.5). - Verified IOUSBHostDevice::deviceRequest vtable slot in Tahoe's BootKernelExtensions.kc (__ZTV15IOUSBHostDevice at 0xffffff8002e72720): confirmed exact match at slot 374 (0x176, byte offset 0xbb0). - Disassembled Tahoe's /usr/sbin/bluetoothd (FindTransportType at 0x10014c700, Found_USB_Dongle at 0x1000e9559, GetProductAndVendorID at 0x1000edf2a) confirming USB transport matching on 'Bluetooth USB Host Controller' and CSR 0x0a12 descriptor spoofing. Code & Build Modifications (v1.1.0): - IO80211Controller.h: Add full 463-slot Tahoe Skywalk vtable declaration (slots 394..462, offsets 0xc50..0xe70) and exact 0x80 filler size when __IO80211_TARGET >= 260000 while preserving legacy compatibility. - QualcommWifi.hpp/.cpp: Implement Tahoe IO80211Controller pure virtual methods (isCommandProhibited, handleCardSpecific, getDRIVER_VERSION, getHARDWARE_VERSION, getCARD_CAPABILITIES, getPOWER, setPOWER, getCOUNTRY_CODE, setCOUNTRY_CODE, setGET_DEBUG_INFO, getLogger, getFaultReporterFromDriver) and guard un-reserved IONetworkController slots 6..7 on SDK 26.5. - QualcommWireless.cpp: Add non-null vtable slot sanity check prior to installing the shadow vtable hook on IOUSBHostDevice::deviceRequest. - project.pbxproj & Info.plist: Upgrade to Xcode 26.6 (MacOSX26.5.sdk), MACOSX_DEPLOYMENT_TARGET = 26.0, __IO80211_TARGET = 260000, and bump version to 1.1.0. - docs & README: Document macOS Tahoe (Darwin 25) architecture, bluetoothd offsets, and Skywalk IO80211Controller ABI.
